Not sure if yellow armor charge mods are supposed to do this, but when using, for instance emergency reinforcement, the armor charges decay at the same rate as with blue armor charge mods. This makes it very hard to be able to proc emergency reinforcement because I have 10 seconds ( unless I use Time dilation and/or Charged up) before I need to get another armor charge for emergency reinforcement to work. Could be wrong, but I thought when using a yellow armor charge mod the armor charges would stay with no timer until the mod proc'd.
